House Republicans, who are now deliberating the government’s 2018 budget, pledge to eliminate deficits within a decade. Well, good luck with that. It must be obvious that chronic deficits reflect a basic political impasse that can be broken only if majorities in Congress do things they’ve refused to do: trim Social Security benefits; raise taxes significantly; control health spending. There is a giant mismatch between what Americans want from government and what they’ll pay for with taxes.
